I'm having such a hard time waking baby girl up to nurse. Sometimes she wakes up on her own to eat. But most of the time I need to wake her up in order for her to eat. It takes so long to wake her and then keeping her awake is just as hard. She will latch, sometimes quickly sometimes not, but she will go for a few seconds and fall back asleep. I have no idea what I can do to keep her up. Any ideas? Greatly appreciated.
